预制分支电缆是根据设计要求，在主干电缆规定的尺寸部位预制出规定截面的分支电缆。预制分支电缆由主干电缆、分支接头、分支电缆三部分组成，每个分支接头部分均以优良的合成材料采用气密模压，使电缆的外护套材料和注塑的合成材料接合在一起而形成气密和防水的分支接头。本公司可生产主干电缆为单芯或多芯的预制分支电缆GB/T19666-2005《阻燃和耐火电线电缆通则》JJB/T10636-2006Copper-coreExtrudedPlasticInsulatedCableswithPre-fabricatedBranchesforRatedVoltageof0.6/1kVGB/T19666-2005GeneralRulesforFlameRetardantandFireResistantWiresandCables产品表示方法PRODUCTPRESENTATIONMETHODTheprefabricatedbranchcableisthebranchcablewiththespecifiedcrosssectionprefabricatedinthespecifiedsizepartofthemaincable.Theprefabricatedbranchcableisconsistedofmaincable,branchjointandbranchcable.Eachbranchjointismadeofhigh-qualitysyntheticmaterialsandismadebyairtightmolding,sothattheexternalsheathmaterialofthecableandtheextrudedplasticsyntheticmaterialsmaybetightlyconnectedandformtheairtightandwater-proofbranchjoint.Wemaymanufactureprefabricatedbranchcableswiththemaincabletobesinglecoreormultiplecores.Thespecificmodelandspecificationsmayrefertothefollowingmaterials.
